MACHINE FOR WRAPPING AND AFFIXING LABEIZS AROUND RECTANGULAR TABLETS.

Specification of Letters Patent.

Application filed May 6, 1910. Serial No. 559,699.

' gular tablets; the primary object of the invention being to provide a machine of an improved construction whereby labels may be rapidly and efiiciently wrapped and affixed around rectangularbodies such as chocolate tablets inclosed in a covering ma tion grip until the disk again rises with the attached label, the corner stops at the upper terial such as tin-foil.

In carrying out this invention, the labels in pile formation are placed upon avertically movable plunger situated within a provided box-like receiver of rectangular shape in plan and which is of a size about equal to or slightly larger than the labels themselves, said box being open at the top with the exception of the corners which are fitted with angle plates forming stops against which the uppermost label of the pile is pressed by the carrying plunger, the latter for this purpose being suitably weighted or otherwise operated so as to be normally retained inthe up position bywhich the pile of labelsis made to contact with the stops. v On a provided vertical shaft situated near the label box is mounted a horizontal disk formed with a series of through apertures,'say three in number, which disk through the medium of its shaft and provided spur and ratchet gearing is adapted to-be moved intermittently through a third of a revolution so as to bring the disk apertures in turn to rest directly over the label box, a spring catch or the l1ke being employed for retaining the disk in the moved osition.

To t e underside of the disk and at the opposite sides of each of the apertures are formed dependingrlugs, which during the time the disk is being moved to bring the disk apertures in turn over the label box are caused to take up an adhesive from a roller situated in front of thelabel box and which may be supplied with say gum from a provided trough, whereby the depending lugs of each aperture of the disk are effectually gummed before being brought to rest over the label box; and the said disk is 'mounted on a spring so as to be capable of being depressed through the medium of a provided tappet lever, which latter is operated say from a cam shaft at the moment each of the disk apertures is over the label box, which has the eifect of causing the depending lugs of each disk aperture to press upon the pile of labels and take up the uppermost label. The depressing of the disk is such as to cause the plunger with its pile of labels to be lowered slightly in the box, when the plunger is momentarily held in the depressed position by a provided fricend of the box during this operation having the effect of effectually preventingthe second or subsequent labels of the pile being lifted out of the box with the uppermost label. 1

After the disk has been raised by its spring to the normal or up position with the label attached, the said disk is then moved a step forward so as to bring the subsequent disk aperture over the label box and simultaneously therewith the grip on the plunger is, released when the pile of labels is again raised in the box up to the corner stops of the said box, while this same movement of cause the subsequent disk'aperture'to take up a label from the'label box.

Beyond the table is mounted a receiver:

.plate on to which the tablets are .fed, say

from a wrapping machine or from any other source by suitable means; and in con]unc- Patented Nov. 22, 1910;

tion with this receiver-plate is provided a pusher-bar having a horizontal reciprocating movement timing in with the movement oftlie label-carrying disk, which bar at each reciprocation pushes forward a single tablet off the receiver-plate and delivers it on to the label which has been carried by the depending lugs of the disk over the liftingtableLQ An intermittently moving plunger Y subsequent disk aperture takes up a label over upon the tablet now resting upon the table, while thecontinued movement of the 7 pusher-bar. Fig. 2 shows the positionof 'tionary side projections and bring the said which lip first engages against one upstandtially labeled tablet forward off the table downward along with the lifting table by the completely labeled'tablet, the opposite situated over the diskis now operated so "as to pass through the disk a erture carrying the label and depress the ta let and its label along with the lifting-table between statable-into the down osition, which has the effect of releasing tl ie'label from the disk. and of simultaneously turning the opposite ends -of the label into an upstanding posi-' tion; and after the tablet and its label ave been depressed, the disk is raised and the" from the label box so as to bring another label forward at the next movement of the disk. After the tablet and label have been depressed to turn the ends of the latter upward, an intermittently. reciprocating slide formed with an overhanging ip' is operated,

ing end of thelabeLand causes it to belaid said slide has the effect of pushing the parand on to a deliveryv plate beneath a brush by which the other or opposite upstanding end of the label is laid over u on the first turned down ortion of the la e1; the adhesive on the label causing the same to become firmly affixed to the inner wrapper and around the tablet during its passage beneath the brush.

In the drawings at Figuresl to 4 there are illustrated the several sta es in the wrappin and afiixing of a labe around a rectangu ar tablet by the machine herein-\ after described. At Fig. 1 the label 1 is shown in the position it occu ies when carried by the depending lugs of the isk over thelifting table with the wrap ed tablet 2 rest1ng upon the-said label in t e osition 1t occuples after being pushed orward by the the tablet and label after being carried the intermittentl moving plunger. between the stationary si e projections, the label being released from the disk and having its opposite gummed ends beyond the tablet turned into an upstanding position. F1g.3 shows the partially labeled tablet while still resting upon the de ressed table, the inner upstanding gumme end of the label having been turned down upon the tablet by the overhanging lip of the intermittently reciprocating slide during the first portion of its forward movement; and Fig. 4 shows or outer upstanding gummed end of the label having been turned down upon the first turned down portion of the label due to the tablet being pushed ofl:' the table and on to the delivery plate beneath the bruit by the continued forward movement of t 'e ovate? intermittently reciprocating slide; the adhesive on the label causing it to become firmly afiixed to the inner wrapper and around-the tablet during its passage beneath the said brush. To produce thisresult in wrapping and affixing labels 'around'rectan lar tablets, the machine is constructed an operates as will now be described with Fig. 7 is an en elevation of the wrapping machine, and Fig. 7 is a detailed view of the friction grip em loyed. Figs. 8 and 9 are res ectively a si e'elevation and a plan of the abel box and label-carrying disk, detached from the machine.

Referrlng to Figs. 5 to 9 of the drawings the machine consists of standards -3 fitted with a bed-plate 4 provided with end brackets 5 carrying a main shaft 6 which is driven b a belt pulley 7 in the direction indlcated y arrows (Figs. 5 6 and 7). On the bed-plate 4 is mounted a box-like receiver'8 into which the labels 1 in pile formation are placed and which are carried u on the upper'end of a. vertically movable p unger 9 made slidable in a fixed bracket 10, sa1d box -8 being open at the top with the exception of its corners which are fitted with angle plates 11 forming stops for the pile of labels, which latter is normally presse upward by the carrying plunger 9 through the medium of a counterbalanceweight arrangement 12 so as to cause the 1 uppermost label of the pile to contact with the said stops 11.

Near the label box.8 and on the bed-plate 4 is mounted a bearing 13 fitted with a vertical shaft 14 carrying a horizontal disk 15 formed with three openings or apertures 16',

which disk 15 is rotated intermittently through a third of a revolution in the direction indicated by the arrow (Fig. 6) through the medium of its shaft 14, spur gearing 17 and. ratchet-mechanism 18 actuated by a rock-shaft 19 operated from the main shaft Gby crank-mechanism 20 an'd bevel gearing 21 so as to bring the disk apertures 16 in turn to rest directiliy;I a spring-catch 22 tainin liquid gum, which roller 25 is tated 1n the trough 26 from the main shaf t' l'lO through the medium of a bell-crank tappet lever 31 rocking on a stud 32 of a bracket 33,-and the said lever 31 is operated by a cam 34 on the main shaft 6 through a runner 35 at the moment each of the disk apertures 16 is over the label box 8, which movement has the effect of depressing the disk 15 and of causing the depending lugs 24 of each disk aperture 16 in turn to press upon the pile of labels 1 and take up the uppermost label; a spring 36 being employed for retaining the runner 35 in contact with the cam 34. I I

The depressing of the disk-15 by the tappet lever 31 to cause the depending lugs 24 to take up the uppermost label is such as to cause the plunger 9 and its pile'of labels 1 to be depressed slightly in the label box 8 against the action of the counterbalance weight 12, which plunger 9 is momentarily held in the depressed position through the medium of a friction-grip 37 actuated by a spring'connection 38 and an arm 39 situated on the rock-shaft 19, while during the time the (plunger 9 is in the depressed position the isk 15 with'the uppermost label attached is raised to its normal or up position by the spring 28, the corner stops 11 having the effect of effectually preventing the second or'subsequent labels of the pile being lifted. out of the box 8; when the said disk 15 is moved, a st'ep forward so as to bring the subsequent aperture 16 over the label box 8, at which moment the friction-grip 37 is released when the counterbalance-weight 12 comes into operation and raises the plunger 9 in the box 8 and again brings the pile oflabels 1 into cont-act with the corner stops 11 of the said box 8.

The disk 15 in moving a step forward brings the attached; label over a rising and falling table 40 carried in a bracket forming a delivery plate 41 situated on the bed-plate 4, which table 40 is raised to below the attached label at the moment the disk 15 is depressed through the medium of a doubleended lifting-bar42 pivoted on a stud 43 and operated by an arm 44 on the rock-shaft 19; and the said table 40 is held in the raised position by a friction-grip 45 so as to cause it to rest immediately beneath the said attached label.

Beyond the table 40 and on the bed-plate 4 is mounted a receiver-plate 46 on to Whi'Fh the tablets are fed up to a stop 47 by means of an endless belt 48 which is caused to travel in the direction indicated by arrows (Fig. 6) by a crossed-belt 49 driven from the main shaft 6; and in conjunction with this receiver-plate 46is a pusher-bar 50 which is reciprocated at predetermined intervals to time in with the movement of the label-carrying disk- 15 by being carried on an arm 51 which is rocked forward on the 'stud 43 by means of a spring 52 until arrested by a stop 53 formed on the same stud and which is returned'bymeans of a hook 54 operated by an arm 55 on the rock-shaft 19, by which a single tablet 2 is pushed'fon ward at each reciprocation off. the belt 48 and delivered on to the label 1 which has been carried by the depending lugs 24 of the disk 15 over the lifting table 40.

Over the disk 15 an intermittently moving plunger 56 is mounted on a bell-crank lever 57 which is rocked on a stud 58 of the bracket 33 by means of a link 59, doubleended lever 60 pivoted on a shaft 61, runner 62' and a cam 63 on the main shaft 6, so as to cause the said plunger 56 to pass through the disk aperture 16 carrying the label 1 and depress the tablet 2 and its label 1 along with the lifting table 40 between a raised part 41 and a projecting part 41 formed on or carried by the plate 41 and bring the said table into the down position, which has the effect ofreleasing the label 1 from the .disk 15 and of simultaneously turning. the

opposite ends of the said label 1 into an upstanding position; a spring 64 being em-.

ployed for keeping the runner 62 in contact with the cam 63.

After the tablet 2and label 1 have been depressed by the plunger 56 to turn the ends of the said label into an upstandingposition, an intermittently reciprocating slide 65 formed with an overhanging lip 66 is'operated by means of a link 67, double-ended lever 68 pivoted on the shaft 61, runner 69 anda cam 70 on the main shaft 6, which lip 66 first engages against the inner upstand;

ing end of the label 1 and causes it to be laid over upon the tablet 2 resting upon the table 40, while the continued movement of the slide 65 has the effect of pushing the partially labeled tablet 2 forward off the table 40 and on to the delivery plate 41 beneath a brush 71 by which the other or opposite upstanding end of the label 1 l'aid over upon the first turned down' portion of the said label; a-- spring 72 being employed for keeping the runner 69 in contact with the cam 70. I

Th'e tablet 2 is fed by the pusher-bar 50 up to a stop 73', and spring-studs T4 are employed in the delivery plate 41' for'preventing the tablet 2 rising a'fter being-depressed by the plunger 56, while immediately in front of the brush 1 is fixed a spring-plate 75 beneath which the partially labeled tablet is caused to pass on its Way to beneath the brush 71. y

[In action the machine works as follows A row of tablets is fed forward by the traveling belt 48 over the receiver-plate 46 until the foremost tablet 2 rests against the stop 47 and the disk is moved-intermittently through a third of a revolu ion 50 as to first cause the depending lugs 24 of each of the apertures 16 in turn to take u the adhesive from the gum roller 25 before eing brought to rest over the label' box 8, where 'the gummed depending lugs 24 of the disk apertures 16 in turn, due to the depressing and rising of the disk 15, arecaused'to take up a label 1 from the label box 8. The next forward movement of the disk 15 brin s the r pusher-bar 50. The tablet 2 an ends of the said label 1 into an upstanding position (see Fig. 2). The inner upstand-- ing end of the label 1 is now laidover upon the tablet 2 (see Fig. 3) by the overhangfrom the ing li 66 of the intermittently reciprocating slide 65, while the continued movement of the said slide carries the tablet 2 forward on to the delivery plate 41 beneath the spring-plate and brush 71 by which the other or opposite pstanding end of the label '1 is laid over upon the first turned down portion of the", label 1 (see Fig. 4); the adhesive on the label 1 taken 'gummed depending In S 24 causing the label 1 to ecome firm y affixed to the inner wrapper and aroundthe tablet 2 during its passage beneath the brush 71. In this way each disk aperture 16 in turn is caused to take u a label 1 from the label box 8, which attac ed {label in turn receives a tablet 2 around which 'it is ailixed in an automatic manner as above described.
